I have an interest in the modeling, analysis, optimisation and control of networked systems with a focus on drinking water distribution systems (WDS). My research is motivated by imperatives in urban water sustainability – system resilience, efficient resource utilisation, and water quality management. My current work is on the development of optimal control, estimation and tailored mathematical optimisation and analysis tools for `intelligent water systems’. Some examples are:

optimising the water-energy relationship for sustainable operation of WDS and other water resource systems (water-food-energy nexus problems)

optimal placement of sensors and actuators for leakage and fault diagnosis, leakage estimation and localisation,

the optimal placement and operation of pressure and flow control devices for pressure management, water quality control and energy efficiency,

optimal system design and rehabilitation with multiobjective and mixed-integer optimization, and

intermittent water distribution systems.

Other research interests include model predictive control (MPC), robust and optimal control of hydraulic storage structures (eg. for multi-reseirvoir systems and open channels), graph theoretic tools for the analysis of drinking water networks, robust H-infinity control and estimation, optimal control of ocean wave energy converters, and bilinear systems.
